Lockheed Ping-Pong

In 1964 Lockheed proposed a new type of reusable battlefield reconnaissance rocket called Ping-Pong, which was equipped with
solid-propellant rocket motors at both ends of the missile body. It was to be fired on a ballistic flight path to a target several miles
away, take photos with a camera in the centerbody, and fire the rocket motor in the nose to return to the launch site for a parachute
landing.

Ping-Pong was launched from a 4-inch tube, and picked up a slide-on four-fin assembly from the top of the tube. When
the return motor fired over the target area, this fin assembly slid back to the "nose" (now the tail) for stability
on the return flight. Ping-Pong prototypes were actually flight-tested in late 1964, but the project was apparently
abandoned thereafter.
